Deadly bird flu studies to stay secret

(REUTERS) — Two studies showing how scientists mutated the H5N1 bird flu virus into a form that could cause a deadly human pandemic will be published only after experts fully assess the risks, the World Health Organization (WHO) said on Friday.

Speaking after a high-level meeting of flu experts and U.S. security officials in Geneva, a WHO official said an deal had been reached in principle to keep details of the controversial work secret until deeper risk analyses could be carried out.

“There is a preference from a public health perspective for full disclosure of the information in these two studies. However there are significant public concerns surrounding this research that should first be addressed,” said Keiji Fukuda, the WHO’s assistant director-general for health security and environment.
